Image via WikipediaIf you have had the pleasure to install and set up a WebSphere Portal environment, you know that sometimes it can be a big, fat bloated piece of something you'd expect from Redmond.

You will probably see the biggest increase from the Base portal tuning recommendations.Give it as much memory as you can spare and increase the thread pool size -- you should see performance increase just from this. (If on Windows, you can't go above 1.5G, but for a server Windows should always be your last choice.)

After the base portal tuning, try again, then start to do some performance monitoring. If you're a big WCM user, check the caches here and make them bigger.

Links:

a starting point is IBM doc#swg27007059,IBM WebSphere Portal Performance Troubleshooting Guide,it contains basic generic troubleshooting methodology. You may want a methodology like this for your manager or client.. Also a step-by-step guide to the PMI / Tivoli Performance Viewer -- these are definitely worth checking to get basic measurements of your server.

WebSphere Portal and Lotus Web Content Management 6.1.x Performance Tuning GuideBroken out into portal, WCM, database, web, etc components. Has specific parameters to change, but you need to know what you're doing.This document is also somewhere on the IBM side, but the lotus wiki versions allow for updates. (I have even corrected some of their documents.. if only they would conform to the formatting conventions)

About Me

I have worked mostly with small companies / start-ups, building whatever is required and chasing moving targets. I still do some of this, keeping up on technology, tools, and trying to stay bleeding edge. (There's too many edges though.)

I like to know how things work, including the internet, physics, science, chemistry, biology.
